be2net: fix a race in be_xmit()

2012-07-16T15:47:37+00:00

[ Upstream commit cd8f76c0a0c6fce0b2cf23c9bd0123f91453f46d ] As soon as hardware is notified of a transmit, we no longer can assume skb can be dereferenced, as TX completion might have freed the packet.

Add appropriate include for prefetch users

2011-05-23T04:41:57+00:00

After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout. Give them an explicit include via the following $0.02 script. ========================================= #!/bin/bash MANUAL="" for i in `git grep -l 'prefetch(.*)' .` ; do grep -q '' $i if [ $? = 0 ] ; then continue fi ( echo '?^#include ' echo . echo w echo q ) | ed -s $i > /dev/null 2>&1 if [ $? != 0 ]; then echo $i needs manual fixup MANUAL="$i $MANUAL" fi done echo ------------------- 8\<---------------------- echo vi $MANUAL ========================================= Signed-off-by: Paul [ Fixed up some incorrect #include placements, and added some non-network drivers and the fib_trie.c case - Linus ] Signed-off-by: Linus Torvalds

be2net: Fix to prevent flooding of TX queue

2011-05-11T23:10:03+00:00

Start/stop TX queue is controlled by TX queue "used" counter. It is incremented while WRBs are posted to TX queue and decremented when TX completions are received. This counter was getting decremented before HW is informed about processing of TX completions. As used counter is decremented, transmit function posts new WRBs and creates completion queue full scenario in HW. Signed-off-by: Padmanabh Ratnakar Signed-off-by: David S. Miller

be2net: Handle error completion in Lancer

2011-05-11T23:10:02+00:00

In Lancer if a frame is DMAed partially due to lack of RX buffers, an error completion is sent with packet size as zero and num_recvd indicating number of used buffers. These buffers need to be freed and packet dropped. Signed-off-by: Padmanabh Ratnakar Signed-off-by: David S. Miller
